| # Wikipedia EN-FA Accessibility Bridge |
|
|
| Current, attributable English and Persian Wikipedia article snapshots for pages |
| created during a 69-day recency window, plus an EN↔FA |
| counterpart index and static accessibility signals. |
|
|
| The reproducible full baseline is the official **2026-08-01** Wikimedia dump: |
| **6,289,549 English articles without Persian**, **129,821 Persian |
| articles without English**, and **22,277,907 namespace-0 pages** in the |
| combined parity index. Redirects are retained in the parity index but excluded |
| from translation-ready article configs. |
| This first release covers **2026-06-03T00:00:00Z through 2026-08-11T20:23:26Z**. It contains **133,776** |
| current English pages and **12,716** current Persian pages. Among the |
| successfully fetched pages, **133,423 English pages lack a Persian counterpart** |
| and **5,868 Persian pages lack an English counterpart**. Full translation- |
| ready source text is included for **37,592 recently created English gaps** |
| and **1,132 recently created Persian gaps**; pages that already have a |
| counterpart remain in the compact parity index. The larger touched-page change |
| ledger is retained by the builder but is outside this new-entry release. |
|
|
| ## Configurations |
|
|
| - `articles_en`: English wikitext and readable plain text for recently created |
| non-redirect articles that lack a Persian counterpart. |
| - `articles_fa`: Persian wikitext and readable plain text for recently created |
| non-redirect articles that lack an English counterpart. |
| - `parity_index`: compact status and EN↔FA counterpart map for all pages created |
| in the window, including pages deleted or unavailable by fetch time. |
| - `full_articles_en_without_fa`: full English snapshot gaps as of 2026-08-01. |
| - `full_articles_fa_without_en`: full Persian snapshot gaps as of 2026-08-01. |
| - `full_parity_index`: every namespace-0 page in both 2026-08-01 snapshots. |
|
|
| Every article row retains page ID, current revision ID/timestamp/SHA-1, page URL, |
| history URL, and Wikidata QID when available. Recent article rows additionally |
| retain first and last event timestamps in the source window and whether the page |
| was created during that window; full-snapshot rows retain dump date and shard. |
|
|
| ## What “recent” means |
|
|
| Wikimedia's monthly MediaWiki History dumps are used only as a metadata index to |
| discover namespace-0 page IDs created from June 3 through July 31. The live |
| MediaWiki Action API supplies the actual current wikitext, plain-text extract, |
| revision provenance, Wikidata item, and language link. RecentChanges supplies the |
| August portion. Therefore this is a dataset of **current snapshots of recently |
| created pages**, not a dump of every historical revision body. |
|
|
| ## Accessibility fields |
|
|
| The article configs include counts and flags for heading-level skips, images |
| without explicit wikitext `alt=`, tables without detected header markup, math, |
| references, and mixed Persian/Latin directional text. These are triage signals, |
| not a claim of WCAG conformance or a substitute for testing rendered pages with |
| screen readers. A later semantic-HTML pass can prioritize pages flagged here. |
|
|
| ## Privacy and safety |
|
|
| The source history contains contributor metadata, but this pipeline deliberately |
| does **not** retain editor names, IP addresses, user IDs, group membership, edit |
| comments, or blocks. It stores page/revision provenance needed for attribution |
| and reproducibility only. |
|

| ## Translation workflow |
|
|
| This repository is the canonical source layer. Machine translations should go in |
| a separate derived dataset carrying the source page/revision identifiers, teacher |
| model and exact checkpoint, prompt, decoding settings, automated quality signals, |
| and human-review status. Generated translations are not silently mixed into the |
| Wikipedia source rows. |
|
|
| ## Reproduction |
|
|
| The resumable builder and tests live in the Motarjem project. The release manifest |
| records every Parquet shard's row count, byte size, and SHA-256 digest. |
